S (subject) +V (predicate) +IO (indirect object) +DO (direct object) and S+V+O (object) +OC (object complement) are somewhat similar in form, but they can be easily distinguished if the correct methods are mastered, such as:

He gave me a book.

He called me Tom. He called me Tom.

Five basic sentence patterns in English

1, S+V is characterized by the following: the predicate verb is an intransitive verb, which can express a complete meaning by itself, without the object, but sometimes it can be used as an adverbial with adverbs and prepositional phrases.

2. The characteristic of this sentence pattern of S+V+O is that the predicate verb is a transitive verb, which cannot express the complete meaning and must be followed by an object.

3. The characteristic of this sentence pattern of S+V+P is that the predicate verb is a connecting verb, which can't express the complete meaning. It is necessary to add a predicate to express the subject characteristics, identity and state.

4. The sentence pattern of S+V+INO+DO is characterized in that the predicate verb is followed by two objects, both of which are the objects or patients of the action, in which the person refers to the indirect object and the object refers to the direct object. When the indirect object is placed after the direct object, the preposition for or to is often needed. Double-object verbs.

5. The characteristic of this sentence pattern of S+V+O+OC is that although the predicate verb has an object, its meaning is still incomplete, and another component (object complement) must be added to supplement the object.

Extended data:

sentence constituent

S = subject, V = verb;

P = predictive, O = object;

Generally speaking, a sentence consists of two parts, namely, the subject group and the predicate group.

The subject part is generally composed of nouns or gerunds, and the predicate part is generally composed of verbs. For example:

Professor Ward teaches college students English. Ward teaches college students English.

In this sentence, Professor Ward is the subject and the college English teacher is the predicate.

Sentence members are part of a sentence and play a certain role. A sentence consists of different sentence components. The components of a sentence include subject, predicate, object, attribute, complement, adverbial, predicative and appositive. Every sentence has a subject, a predicate and an object.
